David Garza · Answer 1

1/2 X + X - 15 + 1/2 X + 100 + X - 25 = 540

1/2x + x + 1/2x + x - 15 + 100 - 25 = 540

3 x + 60 = 540

3x + 60 - 60 = 540 - 60

3/3x = 480/3

x = 160

Step-by-step explanation:

1/2 X + X - 15 + 1/2 X + 100 + X - 25 = 540

1/2x + x + 1/2x + x - 15 + 100 - 25 = 540

3 x + 60 = 540

3x + 60 - 60 = 540 - 60

3/3x = 480/3

x = 160
